Abstract

The invention relates to a device for emptying refuse containers into a collecting bin (3), comprising a lifting device (5) with a carriage unit (6) and at least one swivel device (20) mounted on the lifting device, on which a receiving device (10) grasps the refuse container. A four-bar guide (30a,b) arranged on the swivel arm (40a,b) and provided with an upper guide rod (31a,b) and a lower guide rod (32a,b) supports the lifting frame (11) with the receiving device (10). The upper guide rod (31a,b) extends beyond its pivot point (34a,b) as far as the collecting bin (3) and forms an actuating lever (33a,b), whereby a cylinder piston device (21) pivots between the free ends thereof and the carriage unit (6). When the cylinder piston device (21) is actuated, its pivot point (25) on the four-bar guide (30a,b) moves along the arc of a circle (25) between both pivot points (34a,b,37a,b) on the four-bar guide (30) on the swivel arm. This improves the limited ground clearance of vertically conveying lifters and increases height capacity for receiving containers onto the inventive device. The cylindrical piston device is substantially protected against damage.

Description

The invention relates to a device for emptying garbage containers in a collection container with one arranged on the collection container Lifting device with a lifting slide and at least one on the Lifting device arranged swivel device with a swivel arm which is arranged a receiving device for grasping the garbage container.

Such an emptying device is, for example, from DE 36 40 132 A1 known. This lifting device has receiving devices for Garbage container and for two household waste bins arranged side by side on. The small household bins are hung on a pick-up comb, attached to a swivel device arranged on the lifting device with which the container is tipped into the collection container.

The disadvantage of this known device is that the height of the Pick-up device specified by the movability of the lifting carriage and is therefore limited. According to the applicable guidelines of occupational safety the garbage containers must be picked up from the ground, i.e. the Lifting carriage must be able to be extended so far down to the Sufficient requirement to also pick up smaller containers from the floor can. This requirement is thereby in the known device achieved that the lifting device extends accordingly far down. however, this significantly reduces ground clearance. Another This is a disadvantage. that the container receptacle inside the side Guide rails is arranged and therefore for the garbage worker Positioning the container on the receptacle is difficult.

This disadvantage should apparently with a device according to DE-OS 41 42nd 307 can be avoided where the container receptacle was made extendable. The operation, i.e. attaching the container to the Recording device easier, but with this known device the lack of or limited ground clearance and thus the height for the container is not affected because the intake from its lowest point on the guide rails only extend horizontally towards the container can be.

DE-OS 26 54 542 describes a lifting and tipping device with a Four-joint guide that carries the container receptacle at one end and that on the other end is pivotally mounted on a swivel arm. The lower Handlebar is extended to the collection container and forms one Actuating lever on which a cylinder piston arrangement acts. in the The retracted state of the cylinder piston arrangement is the four-bar guide with the container holder pivoted downwards so that the container can be included. In this position, both handlebars have the Four-joint guide at an angle downwards. If the cylinder piston assembly is extended, the container holder is up on a circular arc pivoted until the container rim of the waste container from the locking bar is detected. In this position, which also corresponds to the rest position, the Cylinder piston assembly not yet fully extended and the operating lever points obliquely downwards. The pivot point of the cylinder piston assembly on Actuating lever forms the lowest point of the device and defines it the ground clearance. that is available to the vehicle while driving. The piston or pistons of the cylinder piston arrangement is / are thereby Exposed to damage.

Another disadvantage of this known variant is that the cylinder-piston arrangement must have a correspondingly large length, so that Telescopic cylinders must be used.

The object of the invention is, based on DE-OS 36 40 132, the to improve restricted ground clearance of vertically conveying lifters and the To increase the scope for the receptacle height of the containers on the device, the actuator being largely protected from damage should.

This task is accomplished with a device for emptying garbage containers solved, on the swivel arm a four-bar guide with an upper handlebar and a lower link is arranged, which the lifting frame with the Receiving device carries. The upper handlebar is above its articulation point Swivel arm extended to the collection container and forms one Operating lever, one between its free end and the lifting carriage Cylinder piston assembly is articulated, which when fully retracted At the same time, the receiving device is lowered and moved away from the lifting carriage. at Actuation of the cylinder piston arrangement moves the articulation point on Actuating lever on an arc between the two articulation points of the Four-joint guide on the swivel arm.

Advantageous embodiments are set out in the dependent claims described.

The fact that the upper handlebar is extended and thus the lever arm for forms the movement of the receiving device, the pivot point is the Cylinder piston arrangement further up than is the case in the prior art is so that the piston or pistons of the cylinder piston arrangement are not as strong Is exposed to dirt and damage. Furthermore, the The device according to the invention increases the ground clearance because the Cylinder piston arrangement does not protrude downwards.

In the driving position when the pick-up device is on the lifting carriage is pivoted. is the articulation point of the cylinder piston arrangement in the Area between the upper and lower pivot point of the four-bar guide on the swivel arm and in the presence of two four-bar guides in the Space between the two four-bar guides, creating the Cylinder piston assembly is even better protected. This also helps that the distance between the two articulation points of the four-bar guide on the swivel arm is preferably greater than the length of the actuating lever.

Overall, the overall length of the cylinder piston arrangement can be significantly shorter than in the known device, so that no telescopic cylinder is necessary. The radius of the path of movement of the articulation point Cylinder piston assembly on the upper handlebar is throughout Movement sequence less than in the device according to DE-OS 26 54 542nd

The cylinder piston arrangement is for pivoting the Pick-up device on the lifting slide and for swiveling the Receiving device arranged in the pouring opening of the collecting container and trained. The receiving device can be in the lowest position Lift carriage away from it and thus at the same time on one Circular arc can be swung down so that to accommodate the emptying the container not so far down the lifting device must be, as would be necessary if this pivoting process is not would be provided. This training also helps to enlarge the Ground clearance at.

When the receiving device is pivoted out into the receiving position, the Cylinder piston assembly fully retracted. This means. that the Partially extended cylinder piston assembly in the swiveled-in state and when swiveling the waste container into the pouring opening is fully extended.

The lifting frame can be in a superimposed motion after shooting of the waste container is already raised with the lifting slide of the lifting device become. This has the advantage that the locking position of the waste container is out of the reach of operators, causing the Risk of accident is reduced. At the same time, this also results in a Time savings. The container is locked before the end of the Stroke, advantageously between the recording and one Locking bar, which is attached between the swivel arms and the Reaches over the edge of the container.

The articulation point of the swivel arm is preferably above the Articulation point of the cylinder piston arrangement on the lifting slide. The bigger the The distance between the articulation points is and the closer the articulation point is Cylinder piston arrangement at the through the pivot point of the swivel arm vertical, the larger the available swivel angle when tipping into the pouring opening.

The cylinder piston arrangement advantageously has only one Pressure cylinder on. whereby the device is further simplified can be.

For stability reasons, two swivel arms and two Four-joint guides in a double arrangement between the lifting frame and Lifting carriage can be arranged.

If this double arrangement is combined with a hydraulic motor. are the two upper handlebars behind their pivot point at the respective Swivel arm preferably cropped and on its actuating levers connected with each other. In this case, the pressure medium motor is on one Connection point of the actuating lever articulated.

The cylinder piston arrangement can be connected to a container detection system connected control device to be controllable. Advantageously, by the signals coming from the container detection system the whole Device controlled. The control processes include that the lifting carriage and the receiving device in the for each emptying trash can be brought into the correct position. To record of the container is lifted manually or by triggering the container or Data carrier moved up and the recording device reaches under one Carrying on the container, preferably under the edge of the container.

Depending on the type of waste container the container detection system detects the corresponding pouring opening is approached. The separation of Lifting device and pivoting device has the advantage that the lifting frame can be swiveled in at any height of the container empty the container.

A suction device is advantageously arranged on the lifting frame engages the hull of the garbage container during recording secure during the entire emptying process. The one to be emptied Garbage containers are thus fixed early on, before the Locking bar overlaps the edge of the waste container and in this way locked the waste container on the receiving device.

Exemplary embodiments of the invention are described below the drawings explained in more detail.

The collecting container 3 into which the waste container 1 should be emptied, for example, arranged on a garbage truck his. A pouring opening 4 is at the top of the collecting container 3 provided, however, further pouring openings 4 'below the pouring opening 4 may be arranged. as exemplified in FIG. 2 is shown.

On the back of the collecting container 3 there is a side wall 45 Rail 46 arranged in the vertical direction, on which a lifting slide 6 A cable 9 engages on the lifting carriage 6, which pulls over Deflecting rollers is connected to a hydraulic motor 7. By Extending the upper piston 8a and retracting the lower piston 8b the cable 9 moves and thus the lifting carriage 6 in the vertical direction pulled up.

Two swivel arms 40a, b are arranged on the lifting slide 6, which have two Four-bar guides 30a, b are connected to the lifting frame 11. Of the Four-bar guides are only the lower one in the position shown here Handlebar 32a of the front four-bar guide 30a can be seen. Furthermore, on Lift carriage 6 attached the locking bar 19.

The details of the device are shown in Figs. 3, 4a and 4b. It is a double arrangement with two swivel arms 40a, b and two four-bar guides 30a, b, each of which the front components are shown and marked with the letter a. The swivel arm 40a is articulated at the articulation point 41a on the lifting slide 6 and has in essentially a trapezoidal shape. The four-bar guide 30a formed by the upper link 31a and the lower link 32a, which in the Articulation points 34a and 37a on the swivel arm 40a and at the other end in the Articulation points 35a and 36a are articulated on the lifting frame 11, which on its Top carries the pick-up comb 12, which is under the edge of the garbage container 1 takes hold. Furthermore, the receiving device 10 has a suction device 13 on which is arranged on the lifting frame 11 and on the container body creates and fixes this by applying negative pressure.

The upper link 31a of the four-bar guide 30a is on its rear Extends over the pivot point 34a and thus forms one Actuation lever 33a. at the end of the cylinder piston assembly 21 with the piston 23 is articulated at point 25. In the shown in Fig. 3 The pickup device 10 of the lifting slide 6 is pivoted pivoted away, the pick-up comb 12 around on a circular arc the fulcrum 34a moves. This will not only move from Lift carriage causes away, but also a lowering of the Receiving device 10 and thus the receiving comb 12 achieved. In this. Position, the cylinder piston assembly 21 is completely retracted.

The articulation point 24 of the cylinder piston arrangement 21 on the lifting slide 6 is located below the articulation point 41a of the swivel arm 40a. The The distance between points 24 and 41a is very large, the Articulation point 24 almost on the vertical 26 passing through point 41a lies. This creates a very large swivel angle for tipping into the Dispensing opening provided.

Characterized in that the upper link 31a is elongated, the Articulation point 25 of the cylinder piston arrangement 21 above the articulation point 37a and thus in the protected area. When the cylinder piston assembly 21 is extended, the pivot point 25 moves on the circular path 50, the runs between the articulation points 37a and 34a.

The pivoted-in position is shown in FIG. 4a. The piston 23 of the Cylinder-piston arrangement 21 is only partially extended in this position, where the articulation point 25 is between the articulation points 34a and 37a located. This is shown more clearly in the sectional view of FIG. 4b, in which the four-bar guide 30a has been omitted and the view of the Four-joint guide 30b is released. The cylinder piston assembly 21 is also shown in section, and it can be seen that the piston 23 only partially extended. In this position, which is the driving position of the Corresponds to the device, the piston 23 is located with its articulation point 25 in the protected area between the four-bar guides 30a and 30b. Furthermore, the cylinder piston assembly 21 is already in an inclined position, what especially for the power transmission during the swiveling in Dump opening is an advantage.

5 shows the front view of the device. It is about here a cylinder piston arrangement that only has a pressure medium cylinder which is in the middle between the swing arms 40a and 40b is arranged. The upper links 31a and 31b have behind them Articulation points 34a and 34b bent sections 31a and 31b, which the Actuating device 33a, b form, which to a common Guide pivot point 25 for the piston 23. It will make it simple and compact device shelled.

5, the suction device 13 can be seen more clearly, the one Has rubber ring 14 which delimits an interior 16 in which the Intake opening 15 is located. If the garbage container 1 to be emptied with its Container wall rests on the rubber ring 14, is suctioned off by the Air 16 located in the interior through the suction opening 15 in the interior 16 creates a negative pressure that presses the container onto the rubber ring 14.
